| Kandou AI | KANDOU specializes in the design of high-speed, and pin- and energy-efficient chip-to-chip links, SerDes, and associated technologies.Demand for bandwidth in serial links has increased as industries require both high-quantity and high-quality information. KANDOU BUS has developed a unique approach to serial link design that increases the bit-rateand the reach for a given physical communications link and reduces the power consumption. As a result, more bits can be sent per unit of energy, or less energy can be used to achieve a given bit rate.Less energy means available power can be used for more speed, greater battery life, smaller dies or novel designs that shatter many of today’s constraints.Their team of scientists and engineers, based in Switzerland, the UK, and the US, is pushing the boundaries of serial links. | $36.3M | Series C | Nov 17, 2020 |  |
